Hi,
This is the first time i'm adding CO2 to my grow but i'm seeing some yellowing in the top of my plants, i also added more light, is this beginning signs of light toxicity or some other nutrient deficiency ?
At day 25 a start adding CO2 and increased my led strips from 600watt to 780watt, the last couple days i noticed the top leaves starting to becoming more pale.
My grow space is 3,3ft by 4,25ft, i'm thinking even with CO2 maybe 780 watt is too much?
Strain: amnesia
flower day 33
night temp 71f
day temp 84f
humidity day 60-70%
CO2 1000ppm
nutrients: 900ppm/1,8ec, ph 6,0-6,4
